Heating Characteristics

HEATING CHARACTERISTICS

- In HEAT mode, the TED circuits of a given seat are wired in parallel internally in the CCSM.
- The climate controlled seat system draws approximately 24 amperes, with both seats heating, until reaching the set point and then the system operates at a reduced amperage to maintain the climate setting.
- In HEAT mode, the TED can add up to 40°C-60°C (72°F-108°F) to the ambient inlet air temperature as it passes over the TED.
- The system control settings are based on the LEDs above each seat heat switch button on the EATC (3 for Navigator or 2 for Expedition).
- In the LOW setting, the climate controlled seat module is set to maintain TED temperature at approximately 46°C (115°F).
- In the HIGH setting, the climate controlled seat module is set to maintain TED temperature at 65°C (149°F).







- When heating, the CCSM will vary the speed of the fans and the TED duty cycle in order to reach and maintain the temperature determined by the switch setting (closed loop operation). Refer to the above table for heating mode temperatures.
